Patent abstract
Metadata for a content signal is searched by transforming the content signal into different hash formats, each being used to retrieve identifying information from corresponding databases. The identifying information enables retrieval of metadata from metadata databases. These systems and methods enable devices to access a wide array of dynamic metadata from disparate sources through queries that are derived from intrinsic content attributes.
